It is normal for a female dog to vomit before giving birth, and owners do not need to worry too much. This condition in dogs is mainly caused by vomiting caused by the fetus in the abdomen squeezing the intestines and stomach, and may also be accompanied by symptoms such as trembling.

It is recommended to closely observe the clinical symptoms of the dog. If other abnormal symptoms appear, it is recommended to take it to the pet hospital for treatment or consult a pet doctor in time. Under normal circumstances, dogs will yawn, moan, move around frequently, and have watery secretions from their vaginal canals before giving birth. Generally, the dog will give birth within a few hours after the above conditions occur.
